Wake up with itchy bites on arms and a single bite on sole of foot and have tiny blisters on fingers/palm of hand its been going on for about 2-3month?

May not be bites. It is possible that you have something called hand/foot ezcema or dermatitis, since it has been going on for a long time. You also describe tiny blisters which are found in this condtition. While it is treatable, it is not curable. You should see a dermatologist for treatment and to verify the diagnosis.
See a dermatologist. How do you know they are bites? You need a skin specialist to endever to define this. When you go, bring all pills, creams, and soaps that you use. Ask everybody associated with you if they have any similar symptoms.
